Sturgeons are large, ancient fish known for their distinctive bony scutes instead of scales. They belong to the family Acipenseridae and are primarily found in freshwater rivers and coastal areas. Sturgeons are notable for their long lifespans, with some species living over 100 years. They are also known for their unique elongated snouts, which help them forage for food on the riverbed. These fish are famous for producing caviar, a delicacy made from their eggs. Sturgeons are considered vulnerable or endangered due to overfishing, habitat loss, and pollution. Conservation efforts are underway to protect these remarkable creatures and their habitats.
